Abstract
A signal processing device according to an example embodiment includes: a distortion compensation circuit configured to output a signal subjected to distortion compensation processing; a plurality of amplifiers configured to amplify the plurality of input signals including the signal output from the distortion compensation circuit and output the amplified signals as output signals; a calculation circuit configured to calculate a comparison result for at least one of a phase, an amplitude, or an intensity between the input signal and the output signal corresponding to the input signal during a calibration operation of the signal processing device in which calibration signals are used as the plurality of input signals and are input to the plurality of amplifiers; and a controller configured to control whether or not the distortion compensation circuit executes the distortion compensation processing on the calibration signals based on the calculated comparison result.
